connect that coil david mentions as a quad filar arrangement perhaps? It kind of looks that way but the numbering on one end looks reversed. Just a thought.

Bruce beat me to it

RomeroUK has these strands wired in PARALLEL.  I have done the same thing, but without the diodes on the positive rail.

Bruce

hi Bruce, yes, i think Romero might have posted this in reference to your multi-strand work

@Bruce-TPU .I ask this question with respect . You say that we get 7 times the WATTAGE using this technique , is that based on irrefutable experimental work , or just theory .

@Tektron

The pdf is to big to post below I will sort that out soon and post elsewhere and edit this with a link

Here is the link http://www.megaupload.com/?d=CBEF8HUU someone let me know when it stops working and I will repost it

@freemergy850

Thanks I am sure it is only a small part of the puzzle but I felt it was worth pointing out. Irrelevant to the replications because most, including myself, will be using 8 rotor magnets and 9 stator coils

@ Staffman

Very good point about Lenz law and the counter rotation but how does that tie-in with Bill Muller's 15M/14EM configuration that will travel with the rotation. It could be just a nice pretty pattern and the effect is elsewhere

@conrdelectro

You are correct it is just speculation at the moment, until someone has a good enough test bed to try all these combinations to find which works best (if any)
But remember the 'events' as I call them are just the mid-point of a larger event, that being;

the approach of the single magnet towards the single core

the momentary blip of 0v as the magnet centres on the core (at 1000rpm the time frame is very tiny)

the receding of the single magnet away from the single core

This is all happening to every magnet and core simultaneously, just at differing points on their approach.

Also more magnets than coils would suggest that each coil is being affected by more than 1 magnet, for a 9M/8EM would be 1.125 magnets per coil

@Nul-Points

Beautifully put, far better than the semi-coherent ramble I usually come out with.

@powercat     bourne=Waxingradiance. One and the same.

@woopy, nice video

@ ALL

has anyone tried to calculate the difference between N38 (type Romero allegedly used) and N42 (my own and I know of a few others using) Grade of Neos.

I used one of the Gauss calc's from the magnet supplier websites and found a difference of 2.5%

Does anyone think this number (if correct) is significant enough to warrant an increase in rotor circumference to compensate for the slightly more compressed field lines that would be a result of stronger magnets placed at the places designed for the slightly weaker magnets?

I have done a quick video showing the distance my neos interact with each other on a flat plane http://youtu.be/_bv4cnTYb4k can anyone do the same for N38 20mmx10mm?

Apologies for the long post and multiple replies all-in-one style

Keep smiling

subject : magnet and coil polarity.
I am concerned about builders getting the coil made and wired correctly. Awhile back there was a discussion about whether magnets should be attracting or repeling and I think the outcome of that was less cogging if repeling but romerouk said attracting.
When you assemble the coil set wiring you much get the wire polarity right or
they will cancel each other out. For example if the top coil is would clockwise away
and that wire is on top and a north magnet approches the other end of the coil a sign wave of AC will be produced with one polarity as it approaches and another polarity as the magnet leaves the coil. Now think about the bottom coil if it is likewise placed up like the top coil then the magnet passing it will induce the opposite electrical polarities as it passes it because the other magnet pole passes the coil so that wire needs to go to the other side of the FWBR. or the AC sine waves will cancel each other out.

I could not find the brother bobbins at Walmart and Jo-Ann fabrics had none either but the clerk told me how to tell which is which and they have a class on the package which will determine the proper one. I bought the class 15 which seemed to have some extra thickness at the ends toward the center but thinned down near the circumferance. Can anyone verifiy which class the brother bobbins are from the package?

Oh - I just realized that if each coil has its own FWBR on the top and the bottom
it will be ok but I thought that the coils pairs were to be wired in series to get more
volts in which case my point is important and correct if there is only 1 FWBR for
a coil pair.


This stuff is VERY EXCITING.
I read the forum 3 times a day. And can't wait till we nail the real secret to this
generator's performance.
